My research focuses on understanding how paying attention to visual stimuli influences their processing in the brain.
More specifically we are trying to ‘decode’ brain activity as measured by functional MRI while a subject is performing a cognitive task. To this end we use a novel technique called multivoxel pattern analysis. This allows us to test which patterns of brain activity are typical for a given cognitive state. Such a distributed activity approach differs from conventional neuro-imaging analyses methods and may be more sensitive.
This research will provide us with new insights in how the brain implements attentional control, which may be important for understanding attention deficits in clinical populations, such as patients with neglect.
